Abstract

IN COLOR CARTHODE RAY TUBE, A MAGNETIC FIELD OF MASK FRAME CORNER PARTS IS SENSITIVE TO CHANGES IN THE EARTH'S MAGNETIC FIELD, SO RESISTANCE HOLES ARE DRILLED IN CORNER PARTS OF A MASK FRAME TO INCREASE RESISTANCE AND TO DECREASE THE STRENGTH OF MAGNETISM BY MEANS FOR PREVENTING DECLINE OF COLORIMETRIC PURITY OF SCREEN CORNER PARTS. THESE RESISTANCE HOLES ARE ABLE TO ADVANCE DEGAUSSING EFFICIENCY, TO DISPERSE THE EARTH'S MAGNETIC FIELD TO INSERT RESISTANCE PARTS ON THE CORNER PARTS, A MAGNETIC FIELD OF THE INNER CORNER PARTS OF A MASK FRAME IS NOT AFFECTED BY RESISTANCE HOLES.
